Don’t Drive Blind: Secure Your Harris County DWI Attorney Today
Why a Harris County DWI Arrest Demands Immediate Action
A Harris County DWI attorney can be the difference between a dismissal and a life-altering conviction. If you’ve been arrested for DWI in Harris County, you must act fast. Key facts to know:
- You have only 15 days from your arrest to request an Administrative License Revocation (ALR) hearing to fight for your driver’s license.
- A first-time DWI is a Class B misdemeanor (up to 180 days in jail, $2,000 fine), but it becomes a Class A misdemeanor if your BAC was .15 or higher (up to 1 year in jail, $4,000 fine).
- An arrest is not a conviction. Prosecutors must prove guilt beyond a reasonable doubt, and skilled defense attorneys know how to challenge the evidence.
- Collateral consequences include license suspension, ignition interlock devices, insurance hikes, and employment issues.
Facing a first DWI is overwhelming. With 23,075 DWI arrests in Harris County in 2022, it’s a common but serious charge. Texas law enforcement and prosecutors are aggressive, and they begin building their case against you immediately. The clock is ticking on critical deadlines, especially the 15-day window to save your license.
I’m Herman Martinez, founder of The Martinez Law Firm. As a former Chief Prosecutor for the Harris County District Attorney’s Office with over 25 years of experience, I’ve handled DWI cases from both sides. This perspective as a Harris County DWI attorney allows me to anticipate prosecution strategies and build aggressive defenses to protect my clients’ futures.

Understanding Your DWI Charge in Harris County
If you’re facing a DWI charge in Harris County, understanding the law is the first step toward protecting yourself. Let me break down what Texas law says about DWI charges.
Under Texas Penal Code § 49.04(a), a DWI occurs when you are intoxicated while operating a motor vehicle in a public place. But “intoxicated” has two legal definitions under Texas Penal Code § 49.01(2): not having the normal use of your mental or physical faculties, or having a Blood Alcohol Concentration (BAC) of 0.08 or higher.
This means you can be charged even if your BAC is below 0.08, based on an officer’s subjective opinion that you’ve lost the normal use of your faculties. As a Harris County DWI attorney who has prosecuted and defended these cases, I know this subjective element is often a key area to challenge.
Furthermore, “operating” can mean just being in physical control of the vehicle, not necessarily driving down the road. I’ve seen cases where someone sleeping in a parked car with the keys in the ignition faced DWI charges. The most important thing to remember is that an arrest is not a conviction. The state must prove its case beyond a reasonable doubt.
What are the Penalties for a First-Time DWI?
A first DWI arrest is a serious matter with significant penalties. A first-time offense is typically a Class B misdemeanor, but certain circumstances can lift it to a Class A misdemeanor with much harsher consequences.
| Offense Classification | Maximum Jail Time | Maximum Fine | Minimum Driver’s License Suspension | Other Penalties |
|---|---|---|---|---|
| Class B Misdemeanor | 180 days | $2,000 | 90 days – 1 year | Annual DPS Surcharges ($1,000 for 3 years), Ignition Interlock Device (IID) possible, community service, DWI education programs |
| Class A Misdemeanor | 1 year (365 days) | $4,000 | 90 days – 2 years | Annual DPS Surcharges ($1,500-$2,000 for 3 years), Mandatory IID, community service, DWI education programs, more extensive probation |
The jail time and fines are just the start. A conviction triggers an automatic driver’s license suspension and costly annual DPS Driver Responsibility Surcharges for three years. In Houston, where a car is essential, losing your license can disrupt your entire life. That’s why we fight so hard to protect your driving privileges.
How Your BAC Level Impacts the Charge
Your BAC reading significantly impacts the charge. While 0.08 is the legal threshold, where your BAC falls above that line matters.
If your BAC is between 0.08 and 0.14, a first offense is typically a Class B misdemeanor. This is the most common scenario I see in Harris County.
But if your BAC is 0.15 or higher, the charge is automatically improved to a Class A misdemeanor. This means you face up to a full year in jail and a $4,000 fine. The difference between 0.14 and 0.15 might seem small, but it doubles your potential penalties. It’s also worth noting the ongoing national debate on lowering BAC limits to 0.05, showing that DWI laws remain a focus of strict enforcement.
What if There Was an Open Container?
Imagine being pulled over and an officer sees an open beer can in your car. That open container just made your situation much worse.

Under Texas’s open container law, a first-time DWI with an open alcoholic beverage in your immediate possession increases the minimum jail sentence from 72 hours to six days. While still a Class B misdemeanor, this mandatory minimum jail time limits a judge’s discretion and presents new challenges for your Harris County DWI attorney.
Why You Need an Experienced Harris County DWI Attorney Immediately
If you’ve been arrested for DWI in Harris County, waiting to act is a costly mistake. The clock on your case started the moment of your arrest.

The most urgent deadline is the 15-day window to request an Administrative License Revocation (ALR) hearing. If you miss it, your driver’s license will be automatically suspended 40 days after your arrest, regardless of your criminal case’s outcome. In a city like Houston, losing your license can mean losing your job.
Beyond the deadline, evidence disappears, witness memories fade, and surveillance footage is erased. The sooner an experienced Harris County DWI attorney is involved, the better we can preserve evidence and protect your rights. Police and prosecutors are already building their case. You need an advocate who can challenge their evidence and procedures.
At The Martinez Law Firm, we bring a unique advantage to your defense. As a former Chief Prosecutor for the Harris County District Attorney’s Office, I know their strategies and weak points. This insider perspective allows us to build a defense that’s several steps ahead.
An Arrest is Not a Conviction: How a Lawyer Can Fight for You
Let me be clear: an arrest is not a conviction. Many people assume a charge means their fate is sealed, but that’s not true. The prosecutor must prove every element of the case beyond a reasonable doubt—the highest legal standard.
Our job is to create that doubt. Every DWI case has potential vulnerabilities. Was the traffic stop legal? Were field sobriety tests administered incorrectly? Was the breathalyzer calibrated? We scrutinize every detail—police reports, video footage, lab results—to find inconsistencies, procedural errors, and constitutional violations.
These findings are how we win cases. In Harris County, public records show many DWI cases end in not guilty verdicts or dismissals when a defense attorney successfully challenges the evidence. We negotiate aggressively with prosecutors for dismissals or reduced charges, and we are always prepared to go to trial if it’s your best option.
What a Top Harris County DWI Attorney Investigates
Building a strong defense means a thorough investigation. Here are critical areas where errors often occur:
The traffic stop itself is the first place we look. Police need reasonable suspicion for a stop. If their reason is invalid, any evidence gathered afterward could be thrown out.
Field sobriety tests are notoriously unreliable and have strict administration guidelines. We examine every factor—from the road surface to your health—that could invalidate the results.
Breathalyzer machines aren’t infallible. These devices require proper calibration and operation. We investigate maintenance records and potential errors, as medical conditions or even mouthwash can cause false high readings.
When it comes to blood draws, the rules are even stricter. We verify if a warrant was obtained, if the phlebotomist was qualified, and if proper sterilization procedures were followed.
Chain of custody is crucial for all samples. We demand a complete, unbroken chain of custody to ensure the evidence wasn’t contaminated or tampered with.
Finally, we compare police reports against video evidence. Discrepancies between the officer’s report and the video can undermine the officer’s credibility and the prosecution’s case.
This level of investigation is why hiring an experienced Harris County DWI attorney from day one is so critical. The sooner we start, the stronger your defense becomes.
Beyond the Courtroom: Collateral Consequences of a DWI
The penalties for a DWI conviction extend far beyond the courtroom. These collateral consequences can reshape your life long after your case is closed, as detailed by TxDOT’s overview of criminal and administrative penalties.
One of the first is the Ignition Interlock Device (IID). You may be ordered to install this device in your car at your own expense, requiring you to provide a breath sample before the vehicle will start. This is a constant financial and personal burden.

Your insurance rates will skyrocket. A DWI conviction labels you a high-risk driver, often doubling or tripling your premiums for years. Some insurers in the Houston area may drop you completely.
A DWI can threaten your career, especially if you hold a professional license. Professional license risks are serious for nurses, teachers, and others who face disciplinary action, including suspension or revocation of their license.
Employment background checks are now standard. A DWI conviction on your permanent record can limit job opportunities, as many companies are hesitant to hire individuals with a criminal history.
For parents, a DWI can have devastating child custody implications. A conviction can be used in Harris County family courts to argue for reduced custody or supervised visitation.
Finally, a DWI can lead to travel restrictions, as countries like Canada may deny entry to individuals with a criminal record.
These consequences can be more damaging than the initial penalties. As your Harris County DWI attorney, we fight to protect your entire future from these far-reaching effects.
Frequently Asked Questions about Harris County DWI Cases
If you’re facing a DWI charge in Harris County, you likely have many questions. Let’s walk through some of the most common concerns we hear from clients in Houston.
What is an ALR Hearing and Why is it So Urgent?
Your driver’s license is at risk immediately after a DWI arrest, completely separate from your criminal case. This is where the Administrative License Revocation (ALR) hearing is crucial.
You have exactly 15 days from your arrest date to request an ALR hearing. If you miss this deadline, your license is automatically suspended on the 40th day after your arrest—even if your criminal case is later dismissed. The ALR process is independent of the criminal court.
The ALR hearing is your chance to contest your license suspension. Your Harris County DWI attorney can challenge whether the officer had probable cause to stop and arrest you and question the validity of any tests. This 15-day deadline is a primary reason to contact an attorney immediately after an arrest.
Can I Refuse a Breathalyzer or Blood Test in Texas?
Yes, you can refuse a breath or blood test, but Texas’s “implied consent” law means there are automatic consequences. When you get a Texas driver’s license, you agree to provide a sample if lawfully arrested for DWI.
Refusing results in an automatic license suspension—180 days for a first refusal—which is longer than for a failed test. This suspension happens regardless of the DWI case outcome.
Furthermore, Harris County officers can—and often do—obtain a search warrant to compel a blood draw. So, you could face the automatic suspension and have blood evidence used against you. While refusal can sometimes be strategic, it’s a complex decision with immediate penalties. If you’ve already refused, don’t panic—we can still build a strong defense.
How can a Harris County DWI attorney help if I’m a first-time offender?
If this is your first offense, you may have more options available to you. The Harris County District Attorney’s office offers diversion programs for some first-time DWI offenders. Successful completion can lead to a case dismissal, leaving you with no conviction on your record.
An experienced attorney can also work to negotiate reduced charges or favorable probation terms that fit your life. As a former prosecutor, I understand how the Harris County DA’s office operates, which is a significant advantage in these negotiations.
Most importantly, we work to protect your future. A DWI conviction creates a permanent criminal record that affects jobs, housing, and insurance for years. Our goal is to minimize these long-term consequences through dismissal, acquittal, or strategic sentencing. We also guide you through the confusing legal process, ensuring you understand your options at every step.
